めの白色系軽量保温性中空繊維に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a white, lightweight, heat-retaining hollow fiber for obtaining a fabric having heat-retaining properties suitable for cold weather clothing, sports and leisure clothing.
【０００２】0002
【従来の技術】従来、防寒衣料， スポーツやレジャー

。
このような３層構造の布帛は、特に動きやすさを要求さ
れるスポーツ衣料では、重く嵩ばり、自由な動きが阻害
されるという欠点を有していた。[Prior Art] Conventionally, cold-weather clothing, sports and leisure clothing have formed a three-layer structure with a padding between the outer material and the lining, and have achieved heat retention through the thickness of the air layer in the padding. Such a three-layered fabric has the disadvantage that it is heavy and bulky, which inhibits free movement, especially for sports clothing that requires ease of movement.

図ってきた。[0003] In recent years, fabrics coated with metals such as aluminum and titanium have been used as linings to take advantage of the heat-retaining effect of reflecting body heat on the surface of the lining and reducing the amount of heat escaping to the outside of the clothing. Efforts have been made to solve this problem by reducing the amount of batting or not using it at all.

着加工前の準備工程における布帛の微妙な取り扱いによ
る蒸着斑の発生等、いろいろな問題があった。However, with such vapor-deposited linings that have a heat-retaining effect, metals such as aluminum and titanium are vapor-deposited on the surface of the fabric, which increases costs due to the vapor-deposition process and causes delicate damage to the fabric during the preparation process before the vapor-deposition process. There were various problems such as the occurrence of deposition spots due to handling.

った。[0005] Furthermore, the present inventors have previously proposed a method of imparting heat retention properties to fabrics by incorporating fine particles of carbide ceramics into the fibers themselves (Japanese Unexamined Patent Publication No. 63-1).
(No. 95375) However, although this method provides an excellent heat-retaining effect, there is a problem in that the color tone is black, so the color tone of the fabric is extremely limited.

が重くなるという問題があった。Furthermore, in order to solve the problem of color tone, the present inventors discovered white fine particles (hereinafter simply referred to as white fine particles) that have the ability to absorb light energy in the fibers themselves and emit far infrared rays. (Japanese Unexamined Patent Publication No. 1-314716). However, this fiber has a problem that its heat retention properties are slightly inferior to those containing carbide ceramic fine particles, and the white fine particles make the fiber heavy.

The purpose of the present invention is to provide a white lightweight heat-retaining fiber that has good heat-retaining properties.

る。The present invention will be explained in detail below. The white fine particles in the present invention are fine particles of stannic oxide doped with antimony oxide (the weight ratio of antimony oxide/stannic oxide is 0.5/99.5 to 15/85), or fine particles doped with antimony oxide. Fine particles of stannic oxide coated with other inorganic substances (titanium oxide, zinc oxide, calcium oxide, calcium carbonate, zinc carbonate, calcium sulfate, barium sulfate, alumina, etc.) (antimony oxide/stannic oxide/other inorganic substances) The weight ratio of the substance is 0.5/

ある。The fine particles used in the present invention have a particle size of 10 μm or less, preferably 1 μm or less, and more preferably 0.5 μm or less. If the particles are too large, not only will there be problems with heat retention, but when they are incorporated into fibers, problems such as a decrease in spinnability due to clogging of the filter medium in the spinning process and yarn breakage will occur, even if spinning is performed. Even if this is possible, there is a problem of thread breakage occurring during the drawing process.

かも十分な強伸度特性を有する繊維が得られない。The amount of white fine particles added is 0.1 to 20% by weight, preferably 0.5 to 10% by weight, based on the polymer.
More preferably, it is 1 to 7% by weight. If the amount added is less than 0.1% by weight, the desired heat retention property cannot be obtained, and if it exceeds 20% by weight, the spinning property becomes poor and, moreover, fibers with sufficient strength and elongation characteristics cannot be obtained.

含有量を少なくすることができる。In the case of composite spinning, it is preferable that the thermoplastic polymer containing white fine particles be on the inside of the fiber cross section, and the thermoplastic polymer not containing the fine particles on the outside (sheath). By performing composite spinning in this manner, the spinning properties are improved, and the content of white fine particles can be reduced without impairing heat retention.

% is appropriate. If the hollowness ratio is too small, the effect of improving heat retention will be insufficient because there are few air layers in the hollow part, and on the other hand, if the hollowness ratio is too large, a splitting phenomenon will occur during post-processing of the fiber, resulting in poor processability.

る。[Function] The fiber of the present invention has the ability to absorb light energy caused by its electronic structure and emit far infrared rays, and contains white fine particles that exhibit a heat retention effect, and the fiber is hollow. Therefore, it is recognized that the white fine particles effectively contribute not only to the outside of the fiber but also to the air inside the hollow space, and exhibit an excellent heat retention effect. Furthermore, since the fibers are hollow, the apparent specific gravity is small and it is lightweight.
